What is drainage pattern in geography?
Drainage Pattern: It refers to the system of flow of surface water mainly through the forms of rivers and basins.
What do drainage patterns tell us?
Drainage patterns tell us something about the land the rivers are flowing over. Dendritic drainage patterns look like tree branches with lots of twigs. They form in areas with flat and uniform bedrock like sandstone or shale. … They form where the bedrock is faulted and jointed.
What is an example of a drainage basin?

How does vegetation affect a drainage basin?
The amount of rainfall which reaches the drainage basin is also influenced by vegetation cover. A drainage basin covered in dense vegetation will experience high rates of interception root uptake and evapotranspiration – this will reduce the amount of discharge within the basin.
What is the drainage basin system?
Drainage basins refer to the area of land drained by a major river and its tributaries. All rivers flow from the source (often in the mountains) to the mouth (the sea). The drainage basin is regarded as a closed system because water never leaves. Instead it is recycled from one state to another.
Drainage basin hydrological cycle
What is a drainage basin Short answer?
It is an area of land. All water that falls on that land flows into one river. It can flow directly into the river or go through tributaries (smaller rivers that flow into the bigger river) first. One river can drain a large area.
What do you know about drainage?
AFTER HEAVY RAINFALL See also how do you make a barometer The removal of excess water either from the ground surface or from the rootzone is called drainage. Excess water may be caused by rainfall or by using too much irrigation water but may also have other origins such as canal seepage or floods.
What is a drainage basin quizlet?

Where is a drainage basin?
A drainage basin is the area of land around the river that is drained by the river and its tributaries .
How does a water basin work?
The system works by allowing a large collection area or basin for the water. The water then slowly drains out through the outlet at the bottom of the structure. Sometimes concrete blocks and other structures act as a deterrent to slow the water flow and collect extra debris.
What is drainage basin class 9?
A drainage basin or river basin is an area that is drained by a single river system. A water division is considered an upland that divides two irrigation systems that are adjacent to each other. In this blog we discuss drainage class 9 notes in detail.
Is an event in which the amount of water flowing through a river channel overflows its banks?
A flood can develop in a many ways. The most common is when rivers or streams overflow their banks. These floods are called riverine floods. Heavy rain a broken dam or levee rapid icemelt in the mountains or even a beaver dam in a vulnerable spot can overwhelm a river and send it spreading over nearby land.Nov 7 2011
What Is The Role Of A Drainage Basin??
A drainage basin acts like a funnel conveying water that originates as precipitation to a stream lake river sea or ocean. The input is in the form of groundwater runoff or throughflow which are the three main ways in which precipitation in the form of rainwater or snow moves along or through the ground.
What is a drainage basin ks3?
A river basin or drainage basin is an area of land drained by a river and its tributaries . … This can be compared to a sink or basin which catches the water falling into it. The water travels towards the centre and leaves the sink through a plug hole.

What are the characteristics of a drainage basin?
Characteristics of the drainage basin
- Drainage basin – the area of land drained by a river.
- Catchment area – the area within the drainage basin.
- Watershed – the edge of highland surrounding a drainage basin which marks the boundary between two drainage basins.
- Source – the beginning or start of a river.
What is it called when a river overflows its banks?
A. Floodplains The area along a river that forms from sediment deposited when a river overflows its banks is called a floodplain.

What is a drainage basin in geography BBC Bitesize?
A drainage basin is the area of land that it drained by a river and its tributaries. When a droplet of water falls onto the land (as precipitation) gravity will make sure that the water is ‘pulled’ downhill to return to the sea.
How might heavy irrigation in a drainage basin influence the flow of a river?
–larger drainage basins can catch more precipitation so they have a higher peak discharge compared to smaller basins. … -steep sided drainage basins have shorter lag times than shallow basins – water flows more quickly downhill into the river on steep slopes.
What is the drainage and drainage basin?
A drainage basin is a region of land where water from rain or snowmelt drains downhill into a body of water such as a river lake dam estuary wetland sea or ocean. The drainage basin includes both the streams and rivers that convey the water as well as the land surfaces from which water drains into those channels. See also What Is The State Of Matter Of The Mantle?
How does drainage basin affect flooding?
The permeability of the soil and rock in a drainage basin is a big factor in flooding. … The relief and steepness of the basin affects how quickly water enters a river and so how likely a river is to flood. If the river’s valley has steep sides water will quickly enter a river increasing the river’s discharge.
What is a drainage basin A level geography?
A drainage basin is an area of land drained by a river and its tributaries (river system). It includes water found in the water table and surface run-off. There is an imaginary line separating drainage basins called a watershed. Usually this is a ridge of high land.

What is the difference between drainage basin and catchment area?
Catchment area:A river drains the water collected from a specific area which is called its catchment area. River Basin: An area drained by a river and its tributaries is called a drainage basin. A river basin is made up of many different watersheds.
What is meant by drainage basin?
drainage basin also called catchment area or (in North America) watershed area from which all precipitation flows to a single stream or set of streams.
How does heavy rainfall affect drainage basins?
Prolonged rainfall – after a long period of rainfall the ground becomes saturated and is unable to absorb anymore water. … When vegetation is sparse in a drainage basin hardly any rainfall is intercepted more rainfall lands directly on the ground and reaches the river which in turn increases river discharge.
Is the high ground between drainage basins?
An area that is drained by a river and all the streams that empty into it the tributaries is called a drainage basin or watershed. A divide is the high ground between two drainage basins. By studying a map that contains rivers and marking all the tributaries of that river the watershed area can be identified.
Why are basins important?
Catchment basins are vital elements of the ecosystem in which soil plants animals and water are all interdependent. Basins are vital to human existence since they provide clean water for drinking water for growing food and water to nourish plant life which provides the oxygen people breathe.

An area drained by a river and its tributaries is called a drainage basin. The boundary line separating one drainage basin from the other is known as the watershed. The catchments of large rivers are called river basins while those of small rivulets and rills are often referred to as watersheds.
What is flow of water in a channel?
Streamflow or channel runoff is the flow of water in streams rivers and other channels and is a major element of the water cycle. … The discharge of water flowing in a channel is measured using stream gauges or can be estimated by the Manning equation. The record of flow over time is called a hydrograph.
Is drainage a basin?
A drainage basin is any area of land where precipitation collects and drains off into a common outlet such as into a river bay or other body of water. … Other terms for drainage basin are catchment area catchment basin drainage area river basin water basin and impluvium.
